Application filed March 22, 1927. Seria1 No.177,324."

This invention relates to furnace structures and more particularly furnaces espe cially designed for use in heating or treating sheet steel, copper or the like material.

The primary object of the invention is to provide a furnace of this character having a novel form of bottom designed to support the sheets of metal in such a way that the sheets of metal will be thoroughly heated.

A still further object of the invention is to provide a furnace bottom constructed of a plurality of bricks of fire-proof material, the bricks having curved enlargements formed on the upper surfaces thereof, and on which the sheet material rests, the curved enlargements being designed to cause the" tongs or tools lnserted 1n the furnace to remove the sheet material, to ride thereover, eliminating the danger of chipping the bricks of which the bottom is constructed.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a sectional View through a furnace, showing the bottom, forming the essence of the present invention in plan.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3 is a sectional View taken on line 33 of Figure 1. V

Figure 4 is a perspective view of one of the bricks.

Referring to the drawing in detail, the furnace embodies the walls 5 and the bottom 6, the bottom including a plurality of bricks constructed of fireproof material laid adjacent tothe walls 5.

The bottom also includes oblong bricks 7 constructed of fire-proof material and laid end to end as clearly shown by Figure 1 of the drawing.

Formed integral with each brick 7 and extending from the upper surface thereof is an enlargement 8, the upper surface of the enlargement being curved as indicated at 9, the ends of the enlargement merging into the en of the brick proper so that a t l inserted in the oven to remove the material under treatment will be guided upwardly over the curved surface 9, eliminating any danger of the tool chipping the brick.

The sides of the enlargement 8 are cutv away defining curved surfaces 10, which provide longitudinal heat' passageways throughout the bottom of the furnace, when the bricks are laid end to end in the contions of the enlargements 8, to the end that heat may contact with substantially the entire surface of the material supported on the furnace bottom.

I claim:

1. A furnace bottom including a plurality of rows of oblong bricks laid end to end, each brick having an enlargement formed on the upper surface thereof, the enlargements having curved upper surfaces, and the sides of the enlargements being cut away defining lateral passageways when bricks are positioned adjacent to each other in the formation of the bottom.

2. A. furnace bottom including a plural ity of rows of oblong bricks, eachv brick having an enlargement extending from the upper surface thereof, the enlargement of each brick having a curved upper surface extending from the ends thereof, the sides of the enlargement being cut away to provide lateral passageways when the bricks are laid in the formation of the furnace bottom.

3. A furnace bottom including rows of bricks laid end to end, the upper surface of each brick being curved from end-to end,

and having lateral cut out portions, said side edges cut away to provide lateral passageways.

5. A furnace bottom including rows of bricks laid end to end, an enlargement 5 formed on the upper surface of each brick,

the enlargement having a curved upper surface and having lateral cut away portions, and said curved surfaces and lateral-- cut away portions defining right angled passageways when the bricks are laid end to end in the formation of a bottom.

In testimony that I claim the foregoing as my own, I: havehereto affixed my signature.
